Thread: Low Damage with Main Team

This question is mainly about why my damage numbers are so low and not about how to beat guild order. Using guild order event as a premise for dmg numbers
I am running a water team in the fire crom guild order event with roughly 45k Power. Right now, my damage feels extremely low and I can barely clear the event.
From each hit, I am doing around 20k-30k damage per hit up to a max of 36k. Each of my bursts are ~100-160k each burst and my full-burst combo is around 420k

Looking at other clear videos like this one, they doing 40~80k per hit . Each burst is ~360k with full-burst around 1.2 mil. Besides skill leveling up each of my weapons can anyone recommend other things I can do to up my damage?

Skill-wise I am using SSR Nike's Def Down and Sniper Shot. I am using SSR Nike's Atk-up.
